1 Q, .1, I bliiplidatiein filed August e, was, Serial No. 511,610.

To all whom it may concern Be it known that I, ,HENnY COLLINET, a citizen ofthe United States; residing'at Chi-j; cago, in the county or \Codk and State 'of Illinois, have inventedcertain new and useful Improvements in Gasolene-Engines, of which the following lsa speclfication.

My invention relates to that class of two tical, sectional view through an engine embodying my present invention. Fig. 2 is an elevation partly in section of a portion of the valve-operating mechanism. Fig. 3 is a cross-section through the cylinder head removed. Fig. 4 is a bottom plan view thereof, and, Fig.5 is'a cross-section through the cylinder head and the upper portion of the cylinder, showing the connect-ions t-herebetween.

Referring to the drawings, 1 represents a piston, arranged within the cylinder 2, and having its rod 3 connected at its lower end to crank t of the shaft 5 ournaled through the crank case 6.

The cylinder 2 -is provided with ports 7, communicating between thecrank case 6 at apoint above the piston 1 when the latteris in lowermost position. Above its center, said cylinder 1s pivoted into lnner and outer walls 8 and 9 respectively, forming a waterspace therebetween. Superposed upon the cylinder 2 is the cylinder head 10, which comprises inner and outer walls, 11 and'12 respectively, forming a water-space 13 there between, the wall 12-being provided, at the lower edge, witha depending flange 16 to fit about the upper edge of cylinder 2. The lower edge of the head has a circular series of openings 15, communicating, when said head is in position upon cylin-' dcr between the water-space 13 of said head and the water-space 17 between walls 6 and 9 of the cylinder, certain of said openings being adapted to receive the inner ends of the studs 14. Threaded upon both ends, the said inner ends being shrewed conformably threaded "bores in the upper I edge of cylinder 2, and the outer ends profj'ectmg exteriorly through openings in, the

upper wall of the head for the reception of nuts 1 1 whereby to rigidly and securely lock. the head upon the cylinder. The. inner. wall 11 of the cylinder head has at its loweredge,

an internal circular flange 18 provided with. l

a central opening forming a valve seat 19, and said inner wall also has a port 20 above said flange, walled at 21 across the waterspace 13, andscommun'icating exterior-1y through the outer wall 12 as clearly shown in Fig. 3, A vertical tubular valve stem guide 22, centrally connects the inner and .outer walls 11 and 12 of .said cylinder head and is arranged in a line above the center of the opening: forming the valve seat 19. I

The valve 23is seated upwardly against the valve seat '19 and has itsstem 24 projecting exteriorly through the tubular guide 22, and a spring 25' coiled about the said valve stem is compressed between the surface of the cylinder head and its outer endv whereby to close said valve against its said seat. Mounted upon the upper surface of the cylinder head is a supporting base 26 upon the upper end of which is intermediately pivoted 'a rocker arm 27 ,having its headed end 28 bearing upon the upper end By the means herein described, Lam enit abl'ed to provide a strong and durable conof valve stem 24 and provided with a yoke. '29 pivoted to its opposite end. 3

struction of cylinder head and valve operating mechanism, which will rarely get out of order, and which may lee-quickly and easily' removed to reseat the exhaust valve, clean out the cylinder and for other purposes.

Having fully described my iiivention, I claim:

In an explosion engine of the character described, a cylinder comprising spaced inner and outer cylinder walls formingtherebetween a cylinder water space, a removable cylinder head including spaced inner and head wall, t

outer head walls providing a head waterspace, a horizontal annular 'plaie connecting the lower ends of thehead mner and outer wallstand rovided with a series of spaced openings or establishing direct and free communicationbetween the cylinder water space and the head water s ace, said annular plate extending inwardly eyond the inner head wall forming a flange-valve seat partially closin the lower end of said inner 7 ieouter head wall being .provided with -21. depending holding annular flange fitting'sn'ugly about,,ithe exterior of the upper end .of the outer cylinder wall to make a steam-tight union between the cylinder and head and to permit of said direct and free communication between the cylinder' and head water spaces, a central depending apertured boss connecting the inner and outer head walls, a stem operating through the'apertured boss, a valve connected with the stem, and means to move the stem.

In testimony whereof I affix my signature in presence of two witnesses.
